convertion spase RGB to HSV

用二维小波包分解得到水平垂直细节系数，据此组合合成图像的边缘，并与传统算子方法对比(Two-dimensional wavelet packet decomposition has been the level of vertical detail coefficient, which images the edge of combinatorial chemistry and operator with the traditional methods)

人脸识别的最基本的算法PCA，主要是描述了特征值法的基本原理，内容很详细。(Most basic algorithm for PCA Face RecognitionFace recognition algorithm is the most basic PCA, mainly describes the basic principles of characteristic value method, content, very detailed.)

图论研究中的图着色问题的matlab程序，非常好用啊！(Study of Graph Theory Graph Coloring Problem of matlab program, very easy to use ah!)

this is a java in mind of evalise thank you very much

说明：  神经网络实例集。包括以下几个程序单层线性神经网络实例、感知器神经元解决较复杂输入向量的分类问题、基于感知器神经网络处理复杂的分类问题、数值分析程序matlab-GUI、用BP网络完成函数的逼近源程序、自组织特征映射应用实例(Examples of neural network sets. Procedures include the following examples of single-layer linear neural network, perceptron neuron input vector to solve more complex classification problems, based on the perceptron neural network to deal with complex classification problems, numerical analysis matlab-GUI, using BP network function source approximation, self-organizing feature map application)

基于小波变换模极大值用于检测信号突变点，非原创，测试可用(Based on wavelet transform modulus maxima for point mutation detection signal, non-original, test available)

说明：  基于OFDR的分布光纤传感技术的研究，仿真了OFDT干扰(The distributed optical fiber sensing technology based on OFDR is studied, and the ofdt interference is simulated)

说明：  利用子程序fast-lot.m,实现对该图像的变化及压缩，并和以为信号做dct后的图像质量相比较。(Using subroutine fast-lot.m, to achieve the changes and compression of the image, and after, and that the signals do dct compare the image quality.)

在DOA估计中，实际测量和理论肯定存在误差，比如通道误差，阵元位置误差，我们提出一种toplitz的预校正方法。(In the DOA estimate, the actual measurement and theory certainly exist errors, such as channel error, array (position errors, we put forward a kind of toplitz or calibration methods. )
